Extension Manager CS5 hanging problem

Hi there,

I have this issue recently that extension manager pops up when I load Dreamweaver CS5. I've just done an update and the following message comes up:

The Extension Manager will now launch and finish updating Dreamweaver.

Extension Manager then comes up and starts Loading Extensions. However at a certain point it just freezes (see pic).

Any ideas on what I can do to fix this? I am running on Windows 7 Home Premium.

Thanks!
